How Portable Oxygen Concentrators Work

The air around you, in your house, or outside, or wherever you are, contains about 80 percent nitrogen and 20 percent oxygen.

If you need oxygen therapy, it's because your respiratory system can no longer get enough oxygen just by breathing in air. So you use an oxygen concentrator, which delivers purer oxygen to your lungs.

Here's how it works:

Your oxygen concentrator takes in air and filters the oxygen from the nitrogen. It then releases the nitrogen back into the air. The concentrator briefly collects the oxygen and then dispenses it back to the patient.

As long as you have it running and set properly, your oxygen concentrator is continually "making" 90 - 95% pure oxygen out of normal air, so you'll have all you need.

Safe and simple

Oxygen concentrators have become more popular and widely used than old-fashioned oxygen tanks. Why use oxygen in tanks when you can "make" all the oxygen you need, simply and efficiently? Plus, the older-style compressed oxygen tanks can leak and cause explosions and fires. While these events are uncommon, they do happen. Oxygen concentrators, on the other hand, pose no such danger.

Oxygen on the go

The other main benefit of oxygen concentrators is mobility. Most of the concentrators AMSR sells are portable, which means they're designed to be used at home or on the go. With a portable concentrator , you'll always have all the oxygen you need, no matter where you are.

Pulse-dose vs. Continuous flow technology

You might have heard about something called pulse-dose oxygen. It's essentially a newer oxygen therapy technology that delivers oxygen through your cannula only when you breathe in. Continuous flow oxygen, by contrast, is constantly flowing through the tubes.

We recommend talking to your doctor about which dosing technology is right for you. Pulse-dose technology can be delivered in a smaller overall package size and will allow for longer battery life. Alternatively, most patients who sleep on oxygen require a continuous flow dosage due to shallow night breathing. Sometimes it's appropriate to use continuous flow oxygen while you sleep and pulse-dose oxygen during the daytime.
